Air Barometer App by Maksym Buradchuk

Requires iOS 15.0 or later. Compatible with iPhone, iPad, and iPod touch.

Unlike most barometer apps that only display sea level pressure, this app can also show the actual atmospheric pressure at your current altitude. This makes the app closer to a real physical barometer and helps you better understand real local conditions.
The app also provides clear pressure charts, allowing you to track changes throughout the day and monitor long-term pressure trends.

Access to the barometer is handled differently in iOS. How apps obtain pressure data Direct sensor access: To read raw atmospheric pressure data from the built-in barometer, an app does not need the "Motion and Fitness" permission. Apple allows the use of the CoreMotion framework (specifically the CMAltimeter class) to obtain relative pressure without a system request. Why "Motion and Fitness" is needed: This permission is only required if the app wants to track steps, floors climbed, activity types (running, walking), or collect historical data about your movements in the background. Internet (weather): An app can also retrieve data from nearby weather stations over the network, but this typically requires access to your location (Location Services) rather than to the fitness features. How to check where the data is taken from Enable airplane mode: Disable Wi-Fi and cellular data. If the app continues to instantly respond to changes in altitude (for example, if you lift your phone from the floor to the ceiling) or updates pressure in real time, it's using the built-in barometer. Check your location: Go to Settings -> Privacy & Security -> Location Services. If the app has access to your location, it may be downloading weather and pressure data for your city from the internet.

The higonokami, known as 肥後守, is a folding pocket knife originating in Miki, Hyōgo Prefecture, Japan, in 1896. This traditional knife lacks a locking mechanism and instead relies on friction to stay open. Users can utilize the swivel action or apply pressure with their thumb on the distinctive lever, called a chikiri, to keep the blade extended and to prevent the knife from folding. The handle of the higonokami is a single piece of folded-over metal.

Dust is your unnoticeable but reliable ally in protecting your premises

Dust is one of the simplest, yet most reliable, and most importantly, free indicators of unauthorized access.

Methods:
1. Photographic
2. Chemical forensic tools
3. Dust trace detection devices

Note: if a violation of the dust layer is detected, it's possible both to find the fact of access and get more data.
